Abstract: A backward compatible connector assembly that facilitates electrical communication between computer subsystems includes a receptacle, a receiver assembly and a conductor array. The receptacle includes a plurality of first connectors having a first connector length, and a plurality of interspersed second connectors having a second connector length that differs from the first connector length. The first connectors include data pins and the second connectors can include ground pins for single-ended signaling. Alternatively, the second connectors can include a plurality of data pins to form differential pairs of connectors for low voltage differential signaling. The receiver assembly includes first connector receivers that receive the first connectors, and second connector receivers that receive the second connectors. The conductor array can include approximately 40 signal-bearing conductors that have interspersed ground lines or signal-bearing lines.

Abstract: An embodiment of a system for controlling a graphical user interface of a device includes a tiltable member, an electrically conductive member, a substrate, a drive circuit, a switch, and signal logic. The tiltable member is configured for tilting by a user. The electrically conductive member is configured to move in response to the tilting. The substrate is spaced apart from the electrically conductive member by a gap and has mutually isolated sense electrodes disposed thereon. The drive circuit provides an electrical drive signal to the electrically conductive member. The switch is centrally located between the sense electrodes, wherein the tiltable member is connected to the switch to enable actuation of the switch in response to tilting of the tiltable member. The signal logic translates capacitance measurements and actuations of the switch into a signal that is indicative of an input function in a graphical user interface.

Abstract: A method for storing data in a fault-tolerant storage subsystem having an array of failure independent data storage units, by dividing the storage area on the storage units into a logical mirror area and a logical stripe area, such that when storing data in the mirror area, duplicating the data by keeping a duplicate copy of the data on a pair of storage units, and when storing data in the stripe area, storing data as stripes of blocks, including data blocks and associated error-correction blocks.
